TEUss.

Specicaton of Letters Patent No. 3,571, dated April 30, 1844.`

To all 'whom t may concern.' y

Be it known that I, EPENETUs A. BEN- NETT, of the city, county, andState of New York, have invented a new and useful Improvement in Trussesfor the Cure of I-Iernia, which is described as follows, reference beinghad to the annexed drawings ofthe same, making part of thisspecification.

Figure l is a perspective view of the truss. The pad A, covering B2',strap C, and buckle D of the pad, are Inadein the usual, or mostapproved, manner. a

The'improvement consists in making use of a single bandof steel or othersuitable material bent to the requisite shape for the` intended purposeand attaching the pad to one of its extremities and the strap to theother in the following manner: This band ot' steel is first curved so asto be made to asa sume a ligure resembling the letter C-it is then bentinward toward the body of the patient and downward obliquely therequisite length to receive the pad which is attached thereto by a-screwand socket--the portion of the steel band thus bent obliquely downwardforming an elastic arm B2 to which the pad is attached in such manner asto cause aapressurel inward as well as obhquely up-ward against theruptured partJ of the body thus rendering the truss more effective inproducing the intended result and cheaper in its construction. y

I do not claim making the spring holding he pad continuous with the mainspring,

Vhat I do claim as my invention and for which I solicit Letters Patent,is,

The peculiar manner in which I form the aforesaid spring arm B2 bygiving the main spring B an abrupt spiral curve at a point distant fromthe extremity of the spring B equal to the length of the required springarm B2, `and then continuing the said bent portion of the springobliquely downward at an angle of about 45 degrees with a hori` zontalplane, or any required angle, forming a spring arm to which the pad isattached, producing the effect above set forth.
